This short movie shows the difference between diffused, double diffused and hard light
Most large modifiers come with two diffusers. A big one for the outer rim and a smaller one that fits between the source of light and the big diffuser, right in the middle of the modifier. Of course, this begs the question how may diffusion layers do you actually need.
Francisco demonstrates that the tradeoff is pretty simple, the more diffused you are, the less power you get. More diffusion also means less contrast.
Less diffusion runs the risk of more spekular highlights (or “hotspots”) and harsher shadows. Both mean exposing every cress, creek, and pipmle in the skin.
Here are samples which make the comparison pretty clear
